1st Class Heat & Air Reviews

We’re proud to say our customers rate our furnace repair service among the best in Dallas.

We had an amazing experience with this company. Our upstairs A/C unit stopped working. James came out quickly and provided us with a fair price. He was kind and very professional. He even came back the same day when we informed him the upstairs unit wasn’t cooling and made some adjustments. If you are looking for a company that is honest, affordable and reliable, this is the business to use. Highly recommended

Once again I have had 1st Class Heating and Air to my home for a thermostat issue. Art came out and was helpful, knowledgeable and extremely friendly. This company is outstanding with service, price, availability and honesty. I highly recommend this company and they will be my go to for any further needs I may have.

Keep Your Furnace Running at Peak Performance All Winter Long

The best way to avoid a furnace breakdown on the coldest night of the year is to make sure it never happens. 1st Class Heat & Air provides professional furnace maintenance for DFW homeowners — thorough, honest, and done right the first time. A yearly tune-up keeps your system running efficiently, extends its lifespan, and catches small issues before they become expensive repairs.

Won't Start or Stay Running

Short cycling points to faulty thermostat, clogged filter, or failing ignition.

Spiking Energy Bills

Sudden cost increases mean worn parts, duct leaks, or a failing blower motor.

Strange Noises

Banging, rattling, or grinding indicate loose parts or cracked heat exchanger.

Yellow Pilot Light

A healthy flame is blue — yellow or flickering signals a carbon monoxide risk.
